新疆电网装上“太空千里眼” 卫星互联网破解偏远地区电力测试难题

Core Viewpoint - The successful implementation of satellite internet-based wide-area distributed testing technology at the 220 kV Yue Electric Shizhan photovoltaic gathering station marks a significant advancement for the Xinjiang power grid, addressing communication coverage challenges in remote areas and enhancing the testing capabilities for new energy systems [1][3]. Group 1: Technology Implementation - The Xinjiang Electric Power Company has completed a pilot application of satellite internet technology, which is the first of its kind in the region for new energy stations [1]. - The pilot project effectively addresses communication coverage difficulties and data transmission instability in extreme environments, which are common in remote areas like deserts and mountains [3]. - The technology combines the advantages of satellite coverage with the flexibility of ground Mesh networks, resulting in the development of a portable Mesh self-organizing communication terminal [3]. Group 2: Impact on Testing Efficiency - The implementation of this technology is expected to increase the wide-area testing coverage of the Xinjiang power grid from 63% to 98% [3]. - The duration of single testing cycles is projected to decrease from 3 days to under 2 hours, significantly improving operational efficiency [3]. - The annual reduction in wind and solar energy curtailment losses is estimated to exceed 3.8 billion kilowatt-hours, translating to an average annual economic benefit of 95 million yuan, based on an electricity price of 0.25 yuan per kilowatt-hour [3]. Group 3: Future Developments - The establishment of a "space-based monitoring system" will enhance the safe and stable transmission of clean energy such as wind and solar power [4]. - Future collaborations with domestic satellite communication companies aim to deepen the research and development of star-ground collaborative technologies [4]. - The exploration of a "low-orbit satellite + drone relay" communication model is intended to shift wide-area testing from post-analysis to real-time warning, facilitating the digital transformation of the power grid [4].
